In △ABC, m∠A = 65° and m∠B = 80°. Select the triangle that is similar to △ABC.

A. △DEF, in which m∠E = 80° and m∠F = 35°
B. △GHI, in which m∠H = 80° and m∠I = 45°
C. △MRT, in which m∠t = 35° and m∠T = 60°
B. △JKP, in which m∠J = 65° and m∠P = 45°

Can you draw an isosceles triangle with only one 80 degree angle?
